Description

 The invention relates to sports and medical simulators and is intended for training and treatment of the spine.

 A device is known for training athletes, which contains sequentially mounted on the frame handles and parallel guides for moving and fixing in a predetermined position of the support roller for the middle part of the spine mounted on telescopic racks, and means for fixing the steps.

 A disadvantage of the known device is that the increase in the amplitude of the bend of the spine is achieved mainly through the use of naturally high mobility of the links of the middle part of the spine, since the device is not structurally provided with elements containing conditions for using mobility and stretching of the entire spine and repositioning of the discs (see a USSR N 1271532, class A 63 B 69/00).

 The closest is a device for training the flexibility of the spine, including sequentially mounted on the frame handles and parallel guides for moving and fixing in a predetermined position of the support roller for the middle part of the spine mounted on telescopic racks, and means for fixing the steps, also equipped with an additional support roller for the upper parts of the spine and a flat swivel support for the legs, mounted on racks in the rails with the ability to move and fix predetermined position, wherein an additional roller rack uprights made similar to the main roller. The device is equipped with a seat mounted in the rails between the main roller and the support for the legs with the possibility of movement. The means for fixing the steps is made in the form of parallel rungs located in the plane of the frame (see ASF USSR N 1750707, M.cl. 4 A 63 B 23/02).

 A disadvantage of the known device is that with its help it is impossible to work out flexibility and stretching in the cervical part of the spine, as well as setting the discs along the entire length of the spine, since it does not have the active effect of a roller, fixing the head and the guide of the spine.

 The aim of the invention is to increase the efficiency of training, prophylaxis and treatment of the spinal column by providing conditions for the simultaneous processing of flexibility, stretching and repositioning of the disc along the entire length of the spine, due to the action of the active roller, fixing the head and guide the spine.

 This goal is achieved by the fact that the simulator contains a frame mounted on supports, sidewalls which are guides for moving and fixing in a predetermined position of the rotary mechanism, the rear part of the frame is made in the form of a guide on which the seat and the mechanism for attaching the legs are mounted with the possibility of longitudinal movement a sunbed is installed in the frame, and under the frame a swivel mechanism pivotally mounted with the possibility of longitudinal movement and circular rotation, consisting of a shaft to which the guide f with the possibility of adjustment in length, a roller is installed in the end parts of the guides, on one side of the shaft extending beyond the lounger, an L-shaped drive lever is installed with the possibility of adjustment in length and angle of inclination, in the front of the frame there are fastenings for fixing the head and axillary areas, the rear part of the frame is made with the possibility of longitudinal movement with the help of a spring-loaded locking lever, on which the mechanism for attaching the legs is mounted with the possibility of longitudinal movement and fixing. The plank bed is made of transverse planks interconnected periodically with elastic washers by a flexible connection. A longitudinal guide is installed on the lounger, made of flexible material, having in cross section two oval protrusions located at a distance of 1-2 cm.

 The proposed simulator will allow you to actively act on the discs of the spinal column due to the rotation of the roller and a sliding longitudinal guide with a seat, with fixed axillary areas or chin on one side and lower legs on the other.

The essence of the invention is illustrated by drawings, which show:
in FIG. 1 - simulator;
in FIG. 2 - drive mechanism;
in FIG. 3 - tension mechanism;
in FIG. 4 - longitudinal guide.

 The simulator consists of a frame 1 mounted on supports 2, the sides of which are guides 3, used to move and fix the pivoting mechanism in a predetermined position (Fig. 2), the rear part of the frame 1, which is a retractable longitudinal guide 4 with a seat 5, is connected in its front parts by means of a spring 6 with a tension lever 7, the handle 8 of which is pivotally mounted to the frame 1, in the middle part of the handle 8 is connected to a flexible connection 9, on which washers 10 are periodically fixed, which engage with the wedge-shaped zom 11, fixed in turn to the lower part of the frame 1. A support wheel 12 is mounted on the support of the rear part of the frame 4, rollers 13 are mounted in front of the rear of the frame 4 under the seat 5 above the guides 3, holes 14 are periodically made along the entire length of the back of the frame 4 , and with the possibility of longitudinal movement, a shank attachment mechanism is installed, on the sleeve 15 of which a hole 16 is made for fixing by means of a finger 17 with one of the holes 14. The shank attachment mechanism on the sides of the sleeve 15 has arcuate shelves 18, the surface of which s is made of elastic material, in the upper part of the arcuate shelves 18 fixed belts 19.

 Under the frame 1, a rotary mechanism is installed (FIG. 2), pivotally mounted with the possibility of longitudinal movement along the guides 3 and fixing, consisting of a shaft 20 mounted in bearings, to which two plates 21 with holes 22 are rigidly attached at a distance from each other, to the plates 21 are fixed with a possibility of adjustment along the length of the guide plates 23 with holes 24, a roller 25 is installed in the upper part of the guide plates 23. A L-shaped lever is attached with a possibility of adjustment along the length and angle of inclination to one side of the shaft 20 Ag 26 of the drive (an electric drive with a shaft rotation of 8-12 revolutions per minute can be used). In the front of the frame there is a shelf 27 with protrusions 28 to which the chin fixation belt 29 or axillary regions fixation belts 30 are fastened, the second side of which is fixed in the front of the frame 1. The deck 31 is fixed to the front of the frame 1 with flexible joints and made of cross bars 32, interconnected periodically with oval washers 33 made of elastic material.

 For a more active impact on the spine, a guide 34 (FIG. 4) is longitudinally laid on a sunbed, having in the longitudinal section two oval protrusions located at a distance of 1-2 cm.

 The device is used as follows.

 To install the device in the working position, the athlete (patient) or trainer (doctor) moves the rotary mechanism (Fig. 2) along the guides 3 and fixes in the place of impact on the spine, middle (lumbar) or in the upper (thoracic) part of the spine, adjusts by moving the plates 23, the height of the roller 25, then the athlete (patient) sits on the seat 5, fixes the shin attachment mechanism with the help of the finger 17 and the holes 14, 16, puts the legs in the arched shelves 18 and fixes them with a belt 19. After lies on a sunbed 31, passes the belts 30 from the lower part of the axillary regions and fixes by the protrusions 28. Then the athlete (patient) or trainer (doctor) using the lever handle 8 pulls himself with his left hand, and one of the washers 10 of the flexible joint 8 is inserted into the wedge-shaped groove with the right 11 and by means of a reciprocating movement, by means of a lever 26 acts by a roller 25 on the planks 32 of the sunbed 31, which in turn act on the spine. In this case, the ligaments not only at the site of action of the roller 25, but along the entire length to the cervical vertebra are stretched and the mobility of its disk increases.

 For a better effect on the spine, a guide 34 is placed on the sunbed 31 in the region of rotation of the roller 25 (Fig. 4) so that the spinal column enters between its oval protrusions, this will allow the guide 34 to align it further while stretching the spine, since the guide 34, made of resilient elastic material tends to take its original shape.

 To stretch the cervical vertebra and give it flexibility, fix the head with a belt 29, everything else is repeated, which also allows you to stretch the ligaments of the cervical vertebra, improving its mobility, while freeing nerve fibers from being clamped.

 Increasing the height of the roller 25 and the tension force of the spring 6 using the handle 8, increase the tensile strength of the spine and increase its flexibility.

The advantage of the proposed simulator compared with the prototype is as follows:
- provides flexibility along the entire length of the spine, including the cervical;
- promotes stretching, repositioning of the spinal discs and fixation in this position for the necessary time, which in turn, during long and regular exercises, improves the general health condition (because nerve fibers pass to all organs between the discs), eliminate spinal curvature due to overgrowing of the formed wedge-shaped gaps between the disks, contributes to increased growth.
